Description

[Technical field]

[0001] The field of the invention is that of logistics.

[0002] More precisely, the invention relates to a package or a logistic conveyance, ie a container for sending objects between two destinations by means of a package. [Background technology]

[0003] Packaging such as boxes or cartons are known for safely transporting objects in a very reliable manner.

[0004] Generally, the package comprises a box having a base and a periphery which together define a storage space in which the object to be transported is contained.

[0005] The package also comprises lids movable relative to the box, which can in particular assume a closed position in which the lids close the receiving space of the box.

[0006] To provide protection for the transported object, certain packages include means for retaining the transported object within the box.

[0007] Retention means are known in the form of foam panels integrated into the box and into the lid. The foam panels can be applied to the box as required, in other words, the foam panels can be integrated into the box only if their presence is required.

[0008] More precisely, the foam panels are integrated into the bottom of the box, possibly into its periphery, and into the lid.

[0009] The object to be transported is then inserted into the storage space such that it contacts the foam and is retained by at least the base foam and the lid foam.

[0010] This type of holding means presents serious drawbacks in terms of its thickness, in other words the volume it occupies in the containment space of the box, and in the waste management of this type of disposable product.

[0011] In fact, the foam takes up a large part of the containment space of the box, but it has elastic properties and forms a deformable retention means, effectively adapting itself to the contours of the object to be transported, thus fixing it.

[0012] However, depending on the size of the object, several packages must be prepared.

[0013] For example, the same box cannot be used for bulky objects and small sized objects.

[0014] In the case of small-sized objects, if a box or package suitable for large-sized objects is used, the foam will not deform properly in contact with the small-sized object, and therefore the small object may move within the storage space of the box with the risk of being damaged.

[0015] On the contrary, if a large-sized object is inserted into the storage space of the box intended to store a small-sized object, the package may become unusable due to lack of sufficient space in the storage space, and therefore the lid cannot be properly closed to actually block the storage space of the box. As a result, the object is not really protected. In addition, it is visible to the person who carries the package, which may lead to the risk of theft of the object.

[0016] As a result, shippers or packing professionals must have different sized packages depending on the size of the object being shipped.

[0017] Moreover, even if the package can be folded into a "flat" storage or packing position, the foam still adds bulk to the package when not in use.

[0018] In fact, folding the package can optimize its non-use volume. However, compressing the foam when folding the device can impair its effectiveness to protect the object being transported. When the foam is compressed, it loses its elasticity and may not expand properly upon decompression. This is even more true the longer the foam is compressed.

[0019] Therefore, to avoid this loss of elasticity, it is necessary to avoid excessive compression of the foam, which results in only partial reduction in the non-use volume of the package.

[0020] Storage of the packages in working or partially folded or separated form therefore requires having a large area, in fact the foam is separated from the box for packages of various sizes, this therefore means high storage costs which are generally charged to the end consumer.

[0021] According to another known technique, the holding means appears in the form of a plastic envelope into which the object to be transported is slid. The envelope is then deformed so that its walls come into contact with the object to be transported and fix it in its position.

[0022] According to a first type, the envelopes may be integrated into the bottom of the box and their deformation may be achieved, for example, by heating the material so as to shrink it, which then hardens in contact with the object.

[0023] One drawback of this solution lies in the fact that when the deformation of the envelope is achieved by heating, not everyone can achieve the deformation of the envelope, since this technique requires the use of specific heating devices.

[0024] Indeed, only specialists can modify the envelope, since heating means, such as thermal heaters, must be used, which would require special training.

[0025] Moreover, if the envelope is fixed to the bottom of the box, this can be a serious drawback to the integrity of the box, especially if the box is a carton, as too much heat can burn and destroy the carton.

[0026] Moreover, inserting the object to be transported into the envelope may be difficult or impossible (depending on the respective dimensions of the object and the envelope).

[0027] This is particularly evident when the object to be transported is to be inserted into the envelope once the box has been formed, i.e. once the receiving space has been defined, the edges of the box in particular represent a significant obstacle to the insertion of the object into the envelope.

[0028] To alleviate this, it may be necessary to first insert the object into the envelope, then form the box, and finally deform the envelope.

[0029] This means that long processing times are required, especially to transform the envelope or form the box, which can be detrimental for a professional and even impractical for an individual.

[0030] Also, according to a second type, the envelope may be fixed to a tray intended to be contained in a box. In this case, an object is inserted into the envelope, which is then deformed by stretching its two walls and folding the edges of the tray to confine the object, in order to fix and hold it. Once this is done, the folded tray can be inserted into the box and then a lid can be closed on the box.

[0031] These retention means also have certain drawbacks.

[0032] In fact, inserting the object into the envelope does not cause problems, but the deformation of the tray, especially the folding of its edges, becomes a complicated handling and even impracticable if the object is bulky and the envelope to be deformed strongly resists the deformation. The deformation of the envelope is therefore time-consuming and can be unpleasant for specialists, who therefore perform incomplete deformation or even propose larger sized packages, which leads to increased transportation costs for the end consumer.

[0033] In addition, this requires simultaneous storage of the box, lid and holding means, which represents a detrimental overall volume and therefore additional costs that are often passed on to the final customer.

[0034] To address these shortcomings, means for pulling the tray towards the lid have been designed.

[0035] These tensioning means in particular comprise elastic members fixed to the tray, which the user can pull to bring the tray closer to the lid, thus trapping the object to be transported between the tray and the lid.

[0036] Once the object is contained, the fastening means is then used to retain the pulling force originally applied by the user, thus freeing the user.

[0037] These fastening means appear in the form of hooks intended to maintain the elastics relative to one another.

[0038] However, even though this solution contributes to good retention of the objects within the package, it can still be improved.

[0039] Indeed, these retention means require an effort from the user, who must simultaneously achieve traction and maintain the traction initiated and then use the fastening means.

[0040] It therefore happens that the user may lose the benefit of the traction he has initiated while manipulating the fastening means. Summary of the Invention

[0041] The present invention has, inter alia, the object of alleviating the drawbacks of the prior art.

[0042] More precisely, the invention aims to propose a solution for automatically retaining the objects to be transported in a package.

[0043] Furthermore, the present invention aims to provide such a solution which is easy to implement and does not require special handling by the user.

[0044] It is also an object of the present invention to provide a solution of this kind that is long-lasting.

[0045] These objects, and others which appear hereinafter, are achieved by the present invention, which is directed to a package for transporting an object, the package comprising: a box having a storage space defined by a base and a periphery substantially perpendicular to the base; a lid that can be put into a position to close the box; a tray accommodated in the accommodation space and movable relative to the base between a rest position in which it is located adjacent to the base and an operating position in which it is spaced from the base and holds the object against the lid; - means for returning the tray to its operative position, The package is foldable, and the return means comprises: a cross brace movable between a flattened position in which it is crushed flat between the tray and the base and an extended position in which it presses the tray back against the base; a return member fixed to the cross brace and tending to place the cross brace from its flat position to its deployed position.

[0046] The cross brace and return member allow the tray to be automatically pushed back towards its operative position so that when the lid closes the receiving space, objects placed on the tray are maintained between the lid and the tray.

[0047] Thus, objects can be shipped without the risk of being damaged during transport and of being struck by the edges of the box if the box is handled vigorously.

[0048] Moreover, retaining the object in the box does not require any effort from the user, since it is the return member that provides containment of the object between the tray and the lid from the moment the lid is in the position closing the storage space.

[0049] According to a first advantageous embodiment, the cross brace comprises a first arm and a second arm movably connected relative to each other, each arm having a first end movably connected relative to the tray and a second end movable along the bottom, the return member appearing in the form of an elastic material connecting the second end of the first arm or the second end of the second arm to the box and urging the second end of the first arm closer to the second end of the second arm.

[0050] The tension of the elastic material automatically places the tray in its operative position.

[0051] Therefore, by adjusting the tension of the elastic material, the force with which the tray presses objects against the lid when the lid closes the storage space can be controlled.

[0052] Preferably the connection between the elastic material and the box is located vertically or substantially vertically above the first end of the arm to which the elastic material is connected.

[0053] This favors pulling of the first end on the bottom to push the tray back towards its operating position.

[0054] According to a preferred embodiment, the package comprises two elastic pieces each connected on the one hand to the arm and on the other hand to the bottom of the box.

[0055] The use of two elastic members ensures synchronized movement of the two arms to push the tray back towards its operating position.

[0056] Thus, the risk of the tray becoming stuck within the package is limited or even eliminated.

[0057] Therefore, the object being transported is properly retained in the receiving space between the tray and the lid.

[0058] According to a second advantageous embodiment, the cross brace comprises a first arm and a second arm movably connected to each other, each arm having a first end movably connected to the tray and a second end movable along the bottom, the return member appearing in the form of an elastic material connecting the second end of the first arm to the second end of the second arm and bringing them closer together.

[0059] This allows the tray and return means to be removed from the package, particularly when they are not required for use or for storing the package.

[0060] Moreover, access to the return means is facilitated, in particular for maintenance of the return means.

[0061] According to a third advantageous embodiment, the cross brace comprises a first arm and a second arm movably connected relative to each other, and the return member is a torsion spring fixed to the first arm and the second arm, the torsion spring tending to move the first arm away from the second arm.

[0062] This allows the tray and return means to be removed from the package, in particular when they no longer need to be used or for storing the package.

[0063] Moreover, access to the return means is facilitated, in particular for maintenance of the return means.

[0064] Additionally, the torsion springs can be easily adjusted as needed and can be embedded in the first and second arms, for example for protection.

[0065] Preferably, the package comprises two torsion springs.

[0066] The use of two judiciously placed torsion springs can reduce the risk of the arms kinking during their movement.

[0067] Advantageously, the box is provided with a groove for guiding the arm in its movement relative to the bottom.

[0068] Thus, the first and second arms are guided during their movement and can push the tray back towards its operative position.

[0069] Thus, snagging of the arms is avoided for better containment of the object between the tray and the lid.

[0070] Preferably, the box is collapsible.

[0071] Thus, when the package is not in use, the box may be folded to facilitate storage and limit the bulk of the package when not in use.

[0072] Other characteristics and advantages of the present invention will emerge more clearly on reading the following description of preferred embodiments of the invention, given as illustrative and non-limiting examples, and the accompanying drawings, in which: [Brief description of the drawings]

[Diagram 3] FIG. 1 is a schematic diagram showing the package with the box in an unfolded configuration. [Figure 4] FIG. 2 is a schematic diagram showing a tray and a returning means according to the first and second embodiments. [Diagram 5]FIG. 10 is a schematic diagram showing a tray and returning means according to a third embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0074] 1, a package 1 according to the invention comprises a box 2 defining a storage space in which at least one object O to be transported is accommodated, and a lid 3. The lid 3 is intended to close the storage space of the box 2.

[0075] The box 2 has in particular a bottom 21 and a peripheral edge 22, the peripheral edge 22 being a first panel 221; a second panel 222 opposite the first panel 221; - a third panel 223; a fourth panel 224 opposite the third panel 223.

[0076] According to the preferred embodiment shown in figures 1 to 3, the lid 3 is fixed to the peripheral edge 22 of the box 2. More precisely, the lid 3 is attached in a movable connection to the third panel 223.

[0077] With reference to FIG. 3, the lid may comprise vertical sides 25 forming a support between the lid 3 and the base 21 to hold the lid 3 when it is closed on the box 2 .

[0078] According to this embodiment, the box is foldable. Thus, each of the first panel 221, the second panel 222, the third panel 223, and the fourth panel 224 is movably attached to the bottom 21. That is, the panels are: a storage position in which it extends substantially parallel to the bottom 21; - meaning that it can assume an operating position in which it extends substantially parallel to the bottom 21 .

[0079] To maintain the peripheral panels 221, 222, 223, 224 in their operative position, the box 2 is provided with retaining means, not shown in the figures.

[0080] The retaining means may in particular be of the following group: - Magnetic objects, -Additional parts, -transformable, -It can belong to the category of those that use hooks.

[0081] Thus, the package 1 can be placed in a storage configuration or in an operational configuration.

[0082] In the storage configuration, the panels 221 , 222 , 223 , 224 of the box 2 are in their stowed position and the lid 3 is flush with one of the panels 221 , 222 , 223 , 224 of the box 2 .

[0083] In particular, the second panel 222 and the fourth panel 224 are disposed in an overlapping relationship with the base 21 , and the first panel 221 and the third panel 223 are disposed contiguously with the base 21 .

[0084] In other words, the first panel 221 and the third panel 223 are flush with the bottom 21 , and the second panel 222 and the fourth panel 224 are above the bottom 21 .

[0085] The lid 3 is then folded over onto the third panel 223 and the bottom 21. More precisely, the lid 3 covers the bottom 21 as well as the second panel 222 and the fourth panel 224.

[0086] The box 2 further comprises a tray 26 on which the objects O to be transported are placed, as shown in FIG.

[0087] The tray 26 has two positions: a rest position in which the tray 26 is located close to the bottom 21 of the box 2; - an active position in which it is spaced from the bottom 21 of the box 2 and holds the object O against the lid 3, as will be explained below, and is movable in a translational motion relative to the bottom 21 between these.

[0088] The tray 26 has an upper surface intended to face the lid 3 when the lid 3 closes the storage space.

[0089] This upper surface advantageously has a non-slip coating and / or flexible material that favors retention of objects on the tray 26 .

[0090] The non-slip coating can be an additional layer of material applied to the tray 26 .

[0091] In this case, the additional material may comprise a roughness and / or an adhesive coating such as a glue.

[0092] Of course, if an adhesive coating is used, it will be selected to be compatible with the reusable nature of the package 1.

[0093] In other words, the adhesive coating may improve retention of the transported object O within the package 1, but must have the ability to detach itself from the object O when a user wishes to remove the object O from the package 1.

[0094] The additional material may in particular be leather or a synthetic material having properties that allow it to adhere to the objects O to be transported contained in the box 2.

[0095] However, in order to preserve the reusable nature of the package 1, it is essential that the additional layer of material does not allow the retention of contaminants such as dust, sand or other elements that may interfere with the adhesion of the object O to be transported on the rigid element 26, i.e. the tray.

[0096] In the case of a flexible material, foam can be used, which must in particular be deformable to better fit the contours of the object O to be transported.

[0097] To enable the movability of the tray and to enable the object O to be held against the lid 3 , the tray 265 is moved by return means 27 .

[0098] The return means in particular comprise a return member 271 .

[0099] And the return member 271 is a binding configuration which exerts a first force separating the tray 26 from the base 21; a release configuration in which it exerts a second force releasing the tray 26 against the base 21 .

[0100] The first separating force is preferably greater than the second separating force.

[0101] Thus, the return member has a tendency to return to its released configuration, thereby placing the tray 26 in its operative position.

[0102] This tendency of the return member 271 to return to its released configuration therefore makes it possible to press the object O to be transported against the lid 3 .

[0103] According to a preferred embodiment illustrated by FIGS. 1 to 4, the return means 27 further comprises a cross brace 272 inserted between the tray 26 and the bottom 21 of the box 2 .

[0104] The cross brace 272 can be in a flattened position where it is crushed flat between the tray 26 and the base 21 and in an extended position where it presses the tray 26 back against the base 21 .

[0105] The cross brace 272 includes a first arm 273 and a second arm 274 movably connected relative to one another in a cross shape.

[0106] In particular, the first arm 273 and the second arm 274 are movably connected about a shaft 275 .

[0107] The first arm 273 has a first end 2731 connecting it to the tray 26 and a second free end 2732 .

[0108] Similarly, the second arm 274 has a first end 2741 connecting it to the tray 26 and a second free end 2742 .

[0109] The first arm 273 and the second arm 274 are preferably mounted for rotation relative to the tray 26 .

[0110] And the return member 271 is connected to the cross brace and changes the angle A between the two arms 273, 274 of the cross brace 272.

[0111] More precisely, with reference to FIG. 5, an angle A is defined between the first arm 273 and the second arm 274 in the triangle formed by the first arm 273, the second arm 274 and the tray 26.

[0112] And, the transition of the return member 271 from its restrained position to its released position causes a reduction in the angle A and therefore a lifting of the tray 26 relative to the base 21 .

[0113] Conversely, when a force is applied to the tray 26, the angle A increases and the tray 26 is lowered toward the bottom 21.

[0114] To facilitate movement of the tray 26 , a second end 2731 of the first arm 273 and a second end 2742 of the second arm 274 are attached to a groove 28 formed in the box 2 .

[0115] More precisely, the groove 28 is made in a first panel 221 and a second panel 223 of the peripheral portion 22 .

[0116] According to the first and second embodiments shown in FIG. 4, the return member 271 takes the form of an elastic material 277 .

[0117] According to the first embodiment, the elastic material 277 is connected to the second end 2732 of the first arm 273 or to the second end 2742 of the second arm 274 on the one hand and to the box 2 on the other hand.

[0118] More precisely, the elastic material 277 is connected at each of its ends to the second end 2732 of the first arm 273 or to the second end 2742 of the second arm 274 .

[0119] The connection between the elastic material 277 and the box 2 is provided between the two ends of the elastic material 277 .

[0120] The connection of the elastic material 277 to the box 2 can be realized on the periphery 22 or on the bottom 21 .

[0121] Advantageously, the return means 27 comprises two elastic members 277, namely a first elastic member 277a and a second elastic member 277b.

[0122] And in this case, a first elastic member 277a connected on the one hand to the second end 2732 of the first arm 273 and on the other hand to the box 2; and A second elastic member 277b is connected on the one hand to the second end 2742 of the second arm 274 and on the other hand to the box 2.

[0123] According to the second embodiment, the return member 27 comprises an elastic member 277c connecting the first arm 273 and the second arm 274 to each other.

[0124] More precisely, the elastic material 277 c is connected to the second end 2732 of the first arm 273 and to the second end 2742 of the second arm 274 .

[0125] According to an advantageous embodiment not shown in the figures, the package 1 may comprise several elastic members 277 c connecting the second end 2732 of the first arm 273 and the second end 2742 of the second arm 274 .

[0126] According to a third embodiment shown in FIG. 5, the return member 271 appears in the form of a torsion spring 276 .

[0127] A torsion spring 276 is fixed to the first arm 273 and the second arm 274 and tends to move the first arm 273 away from the second arm 274, ie, to reduce the angle A.

[0128] More precisely, the torsion spring 276 is mounted around the shaft 275 and comprises a first branch 276 a connected to the first arm 273 and a second branch 276 b connected to the second arm 274 .

[0129] Preferably, the return means comprises two torsion springs 276 mounted around a shaft 275 .

[0130] And, when the cross brace 272 is in its flat position, each torsion spring 276 is constrained and its two branches 276a, 276b are brought closer together.

[0131] Each torsion spring 276, by its transition to its released position, urges the first branch 276a away from the second branch 276b, thereby enabling the cross brace 272 to be in its deployed position.

[0132] And, the distance D between the second end 2732 of the first branch 273 and the second end 2742 of the second branch 274 is narrowed as the cross brace 272 transitions from its flattened position to its deployed position.

[0133] According to the second and third embodiments, since the return means 27 is not coupled to the box 2, the tray 26 and the return means 27 can be completely removed from the package 1 when they are not in use.

[0134] Furthermore, when the cross brace 272 is in its flat position, each elastic member 277 is constrained and tensioned between the box 2 and the arm 273, 274 to which it is connected, or between arm 273 and the second arm 274.

[0135] Each resilient member 277, by its transition to its released position, draws the second ends 2732, 3743 of the respective arms 273, 274 towards each other, thereby enabling the cross brace 272 to be placed in its deployed position.

[0136] And, the distance D between the second end 2732 of the first arm 273 and the second end 2742 of the second arm 274 is narrowed as the cross brace 272 transitions from its flattened position to its deployed position.

[0137] To enable the safe transportation of an object O, a package 1 according to the invention can be used.

[0138] For this purpose, the box 2 is formed by placing the panels 221, 222, 223, 224 in their working positions.

[0139] In other words, the peripheral edge 22 is formed.

[0140] The object O is then inserted into the box 2 and placed on the tray 26 .

[0141] Once the object O is correctly positioned, the lid 3 can be placed on the rim 22 to close the storage space.

[0142] The cross brace 272 is then placed in the deployed position by the return member 271 and the return means 27.

[0143] This, in turn, makes it possible to maintain the object O contained between the lid 3 and the tray 26.

[0144] Thus, even if the package 1 is disturbed during its transportation, the object O remains perfectly safe between the tray 26 and the lid 3 .

[0145] The package 1 thus closed may then be shipped via the normal distribution channels.

[0146] Advantageously, the package 1, in particular its box 2 and its lid 3, may be made from extruded polypropylene, in particular as sold under the commercial names Akylux, Akyplein and Akyboard by the manufacturer DS SMITH®, or from expanded polypropylene, i.e. in the form of a foam, as sold by the company Storopack®.

[0147] Thus, the object O can be transported in perfect safety by the package 1 just described, even if the package is disturbed between the two destinations during its dispatch.

[0148] In fact, the return means 27 make it possible to place the tray 26 in its operative position and thus to prevent the movement of objects O in the storage space between the lid 3 and the tray 26 .

[0149] Moreover, in the case of the first embodiment shown in Figure 4, the return means 27 and the tray 26 form a removable assembly which can be removed if the object O to be transported is sufficiently large and is maintained in place solely between the lid 3 and the bottom 21 of the box 2.

[0150] Moreover, the guidance of the tray 26 by the grooves 28 in the box 2 makes it possible to avoid jamming of the tray 26 during its movement from the rest position to the working position.

[0151] This will enable Package 1 to be operated for a long period of time.
